Embryology of the reproductive system
14 important questions on Embryology of the reproductive system
When is sex determined?
What happens in week 7 in the development of the reproductive system?
Where do the indifferent gonads develop from?
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Via what route do the primordial cells travel?
What is the function of the primordial germ cells?
- the genital ridges
- the mesonephric ducts (connecting kidneys to sinus)
- the paramesonephric ducts
Under what influence will the genital ridges form into sex-specific structures?
What does the presence of the SRY gene on the Y chromosome cause?
- The Sertoli cells produce MIS, which causes regression of the Müllerian ducts
- The Leydig cells produce testosterone and dihydrotestosterone (DHT)
- The testosterone promotes the transformation of the Wolffian ducts into epididymis, seminal vesicles, etc.
- The DHT promotes development of penis, scrotum, and prostate
What does the absence of a Y-chromosome, and thus the absence of the SRY gene cause?
- The absence of MIS causes the development of the Müllerian ducts into the uterus, Fallopian tubes, and the inner vagina
- The absence of testosterone causes the regression of the Wolffian ducts and the development of the female external genitelia
What do the external genitelia form from?
- genital tubercle
- urethral folds
- genital swellings
When does the first development of the male and female external genitelia take place?
What are embryonic rests?
What happens to some of the female embryonic rests?
Which ligament is in the female inguinal canal?
What is the function of the gubernaculum in females?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
